Abstract
The invention provides a hot rolling heat holding cover, which relates to an insulated device by a high temperature blank technique. The hot rolling heat holding cover is arranged above a hot blank after tapping, and comprises an arc heat holding cover and an opening-closing mechanism connected to the arc heat holding cover, wherein the opening-closing mechanism controls the arc heat holding coverto open and close. The hot rolling heat holding cover can greatly reduce the heat loss caused by convection and radiation in the process of machining the hot blank, is easy and practical, has low manufacturing cost, and can be widely used in hot rolling procedures for producing rails, steel plates, seamless steel tubes and the like.
Description
Technical field
The present invention relates to the hot rolling heat holding device of rail, steel plate and seamless steel pipe etc.
Background technology
During hot rolling now, the factory building that though De Re Pei has wind sheltering to keep off the rain in the transmission and the operation of rolling after the heating, still all belong to full open type operation, thermal loss is big, and cooling is fast, face when finishing and still can have setting high temperature for guaranteeing operation, temperature when coming out of the stove needs high again, thereby the energy consumption height, and the rolling front and back temperature difference is big, the workpiece internal-external temperature difference is big when particularly rolling, easily rolling quality is produced harmful effect; And need heat once more toward contact midway.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of minimizing energy consumption, guarantees the hot rolling heat holding cover of rolling quality.
Technical scheme of the present invention is: the present invention is arranged on the top of the after heat blank of coming out of the stove, and is made up of with the opening and closing mechanism that is connected on the arc stay-warm case the arc stay-warm case.
The arc stay-warm case is made up of internal layer, skin and the outer field member of connection internal layer, and ectonexine bends to arc by thin flat plate and forms, and the internal layer of arc stay-warm case and skin are made with stainless sheet steel.
The present invention can significantly reduce the heat exhaustion that convection current and radiation cause, and simple and clear practical cost is low, can be widely used in producing in the hot-rolled process of rail, steel plate and seamless steel pipe etc.
Description of drawings
Accompanying drawing is a structural representation of the present invention
1 is that hot base, 2 is that hot-rolling mill, 3 is that internal layer, 4 is that member, 5 is that skin, 6 is an opening and closing mechanism among the figure.
The specific embodiment
The present invention is arranged on the come out of the stove top of after heat blank of pipe, is made up of arc stay-warm case and the opening and closing mechanism 6 that is connected on the arc stay-warm case, and opening and closing mechanism 6 controls the opening and closing of arc stay-warm cases.
The arc stay-warm case is made up of the member 4 of internal layer 3, skin 5 and connection internal layer 3 skins 5, and internal layer 3 and outer 5 is formed by Thin Stainless Steel plate bending camber.
When needing further to strengthen insulation, the present invention adds heat-insulation layer and outer cover on bilayer.
The present invention can be combined by the counting unit stay-warm case by the requirement of hot base length width etc.
Claims (2)
